Ihor Humeniuk, who is suspected of involvement in the deadly clashes outside the Ukrainian parliament on August 31, is a soldier in the Sich special operations battalion who tendered his resignation on August 29 after expressing discontent with his low wage and expressing a desire to serve in the Armed Forces of Ukraine, Sich battalion commander Oleksandr Pysarenko has said.

"The suspect really is a member of the battalion, but on August 29 he tendered his resignation. In a private talk he said he wished to be transferred to the Armed Forces of Ukraine," he said at a briefing in Kyiv on Tuesday.

Deputy battalion commander responsible for human resources Tetiana Pecherska presented the letter (addressed to the chief of the Main Department of Interior Ministry in Kyiv) and read it aloud, quoting Humeniuk as saying he wanted to resign as "he was dissatisfied with the size of his wage."

Pysarenko stressed that Sich battalion condemns the events of August 31, adding that the courts will decide who is guilty

He said Humeniuk served in the Anti-Terrorist Operation (ATO) zone for seven months and volunteered to forgo rotation, adding that Humeniuk had no disciplinary problems during his service.
